Find and Download Catalog Products
==================================
The Catalog Tab
---------------
After login on the EGP login page you are presented the Catalog tab.
You will see the first subset of entries of the complete EOC Catalog, which you may
restrict by applying up to four different filters.
.. image:: images/find_download/01-Catalogue.png
Additional information for each filter is available.
.. image:: images/find_download/02-FilterHelp.png
Filters
^^^^^^^
On the catalog tab, filters may be activated and deactivated anytime, any number
from zero to four and in any sequence.
Set filters are displayed as buttons at the top of the tab.
Remove the filter by clicking on the "X" to the left of the filter button.
Moving the mouse over a filter button shows the actual filter settings as tooltip.

Filter by Keyword
^^^^^^^^^^^^^^^^^
You may apply domain-specific keywords like elevation, atmosphere, or crisis information
to reduce the number of catalog results.
Click on the edit field to bring up a list of selectable keywords and start typing to reduce them.
To select, click on a keyword or press Enter.
If there is no suitable predefined keyword, you may also enter free text for a full text search.

The keyword filter is applied immediately on clicking on its activation button.
To remove the filter, click on the "X" to the left of the filter button.

Filter by Type
^^^^^^^^^^^^^^
This filter allows you to restrict the displayed catalog entries to a single type of metadata:
- Datasets: products and mosaics
- Dataset Series: collections of products
- Services: web services for geographic data

.. image:: images/find_download/11-TypesColours.png
"Type" is a special filter which is applied immediately when one of the alternatives is selected.
Clicking on the blue Dataset will hide the green Service and red Dataset Series catalog entries.
Filter Management and Sorting
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The situation depicted below shows the Catalog tab with all filters active and consequently with
only two Dataset entries left. You also see four filter deactivation buttons.
You may deactivate a filter independently from the other filters in order to receive more
Catalog entries. Or you may reactivate it with other constraints.
Pushing the "Clear Filters" button deactivates all filters.
You may save the currently active filter constellation for later reuse, load (i.e. activate), or
delete a previously saved filter constellation.
Sort the list Catalog entries by selecting from the "Sort By" menu.

The "Hide Filter Gallery" button saves screen space but leaves the filter setting unchanged.
Push "Show Filter Gallery" to redisplay the filter settings.

In the Catalog entries list, there is always one entry selected (the one with grey background)
with an extent overview map and a preview image attached to the right.
Only the preview for the selected item is shown.
